Ist Astrophytum Coahuilense Ein Naturhybrid? 37
M6000E Heft 2 Februar 1993 Kakten Jahrgang 44 und andere Sukkulenten Kakteen und andere Sukkulenten Monatlich erscheinendes Organ der als Herausgeber genannten Gesellschaften Heft 2 • Februar 1993 • Jahrgang 44 • ISSN 0022 7846 Zum Titelbild: Astrophytum coahuilense (Moeller) Kayser gehört zu den interessantesten Pflanzen innerhalb der morphologisch so variablen Gattung Astrophytum Lemaire. Es ähnelt einerseits in der äußeren Wuchsform genau Astrophytum myriostigma Lemaire: wie dieses besitzt es meist fünf Rippen und ist dicht mit weißen Wollflocken bedeckt. Sobald jedoch die prächtigen, großen Blüten erscheinen wird andererseits klar, daß eine enge Verwandtschaft zu Astrophytum capricorne (Dietrich) Britton & Rose bestehen muß. Sie sind im Schlund orange bis tiefrot gefärbt und bei Befruchtung entwickelt sich eine purpur-violette, samenreiche Frucht. Die überraschende Mischung der vegetativen und generativen Merkmale bei Astrophytum coahuilense aus den Astrophytum-Linien des südlichen und nördlichen mexikanischen Hochlandes ist auch der Grund für einen noch heute andauernden Meinungsunterschied, wie diese schönen Pflanzen taxonomisch oder in ihrer evolutiven Entwicklung einzustufen sind. Einen Lösungsvor schlag hierzu finden Sie in einem Beitrag auf Seite 37. Astrophytum coahuilense sollte man an einem sonnigen Platz pflegen und von April bis Oktober maßvoll wässern. Ein rein mineralisches Substrat, wie beispielsweise Ziegelsplitt mit Sand gemischt, bietet dann nach trockener Überwinterung um 15-20°C die optimalen Voraussetzungen für regelmäßige Blüten während der sommerlichen Wachtumszeit.

The Wonderful World of Cacti. July 7, 2020
OHIO STATE UNIVERSITY EXTENSION Succulents part 1: The wonderful world of cacti. July 7, 2020 Betzy Rivera. Master Gardener Volunteer OSU Extension – Franklin County OHIO STATE UNIVERSITY EXTENSION Succulent plants Are plants with parts that are thickened and fleshy, capacity that helps to retain water in arid climates. Over 25 families have species of succulents. The most representative families are: Crassulaceae, Agavaceae, Aizoaceae, Euphorbiacea and Cactaceae. 2 OHIO STATE UNIVERSITY EXTENSION The Cactaceae family is endemic to America and the distribution extends throughout the continent from Canada to Argentina, in addition to the Galapagos Islands and Antilles Most important centers of diversification (Bravo-Hollis & Sánchez-Mejorada, 1978; Hernández & Godínez, 1994; Arias-Montes, 1993; Anderson, 2001; Guzmán et al., 2003; Ortega- Baes & Godínez-Alvarez, 2006 3 OHIO STATE UNIVERSITY EXTENSION There is an exception — one of the 1,800 species occurs naturally in Africa, Sri Lanka, and Madagascar Rhipsalis baccifera 4 OHIO STATE UNIVERSITY EXTENSION The Cactaceae family includes between ~ 1,800 and 2,000 species whose life forms include climbing, epiphytic, shrubby, upright, creeping or decumbent plants, globose, cylindrical or columnar in shape (Bravo-Hollis & Sánchez-Mejorada, 1978; Hernández & Godínez, 1994; Guzmán et al., 2003). 5 OHIO STATE UNIVERSITY EXTENSION Cacti are found in a wide variety of environments, however the greatest diversity of forms is found in arid and semi-arid areas, where they play an important role in maintaining the stability of ecosystems (Bravo-Hollis & Sánchez-Mejorada, 1978; Hernández & Godínez, 1994; Guzmán et al., 2003). 6 OHIO STATE UNIVERSITY EXTENSION The Cactaceae family are dicotyledonous plants 2 cotyledons Astrophytum myriostigma (common names: Bishop´s cap cactus, bishop’s hat or miter cactus) 7 OHIO STATE UNIVERSITY EXTENSION General Anatomy of a Cactus Cactus spines are produced from specialized structures called areoles, a kind of highly reduced branch. -

Héctor M. Hernández*, Carlos Gómez-Hinostrosa and Gibrán Hoffmann Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México, Apartado postal 70-233, 04510 Mexico D. F., Mexico. *Correspondent: [email protected] Abstract. With the aim of assessing the extent of geographical rarity of Mexican Cactaceae, we calculated the distribution size (area of occupancy) of 142 species from the Chihuahuan Desert. In addition, using 2 variables (number of localities and range size), we preliminarily assessed their conservation status using the current IUCN Red List criteria. The results showed enormous variation in the areas of occupancy, although from the biogeographic and conservation perspective the most exceptional group comprises the extremely narrow endemics (42 species), whose range is restricted to areas smaller than 10 km2. Our results reinforce the reputation of this plant family as exceptionally rare geographically. We suggest that geographical rarity of Cactaceae in the Chihuahuan Desert is a natural phenomenon; however, we propose that the range of several species has been infl uenced by human activities. Regarding the conservation status of the species, 75 of them are categorized as Least concern. The remaining 67 species (47.2%) fall in 1 of the 3 categories of threat (27 Vulnerable, 11 Endangered, and 29 Critically endangered). These fi gures confi rm the critical conservation status of Mexican Cactaceae. -

European Journal of Botany, Plant Sciences and Phytology Vol.2, No.3, pp.1-15, October 2015 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) ON THE TAXONOMY OF CACTACEAE JUSS BY THE EVIDENCE OF SEED MICROMORPHOLOGY AND SDS-PAGE ANALYSIS Lamiaa F. Shalabi Department of Biological and Geological Sciences, Faculty of Education, Ain Shams University, Cairo, Egypt. Biology Department, Faculty of Sciences, Jazan University, Jazan, Saudi Arabia. ABSTRACT Numerical classification of 16 taxa of Cactaceae was studied using combination of micromorphological characters of seeds (using L.M and SEM) and SDS- PAGE analysis. Aspects of seed micromorphology and seed protein variation as defined were recorded and scored comparatively for the OTU's into a data matrix. Phenetic relationships of these taxa were established based on UPGMA-clustering method by using Jaccard coefficient of the NTSYS-pc 2.2 program. The results were compatible with the traditional relationships of some taxa as the split-off of Opuntia humifusa and Astrophytum myriostigma, at separate lines, these results are compatible with their placement in tribes Opuntieae (subfamily Opuntioideae) and Cacteae (Subfamily cactoideae) respectively, at the time, the placement of three taxa Pseudorhipsalis ramulosa, Rhipsalis baccifera Accession 1, and Rhipsalis baccifera Accession 2 together, the clustering of Hylocereus triangularis and Neobuxbaumia euphorbioides together at a unique tribe Phyllocacteae. The findings contradict in a number of cases the traditional studies, as the grouping of Trichocereus vasquezii with the two represents of genus Parodia despite of their placement in different tribes. KEYWORDS: Cactaceae, SDS-PAGE, Seed micromorpgology, SEM INTRODUCTION The Cactaceae are an exciting and problematic group of plants because of their varied morphology, succulence, and their showy flowers (Barthlott and Hunt 1993). -

Cold Hardy Landscape Cacti & Succulents for Central Texas Jeff
Cold Hardy Landscape Cacti & Succulents for Central Texas Jeff Pavlat 3/11 The following is a list of recommended landscape plants for Central Texas. Keep in mind that there is a great deal of temperature variation across the region. Temperatures in outlying areas are in some cases 10 to 15 degrees colder than those in town. The cold tolerances listed are approximate. It is important to recognize that there are a number of factors which determine hardiness. Plants placed on south facing slopes receive more solar heat and tend to have a better chance of being undamaged. Plants also fair better with some overhead protection from a tree or shrub. It also helps for them to be placed where they will not receive direct north wind. Generally, low-growing plants receive more ground heat than taller plants and are less likely to freeze. The state of the plant as it enters freezing temperatures is an important factor as well. For instance, many cacti and succulents will endure considerably colder temperatures when dry rather than wet (In fact, cold and wet is often a lethal combination for many cact i). Plants of the same species originating from different parts of the plant’s native range can also result in higher or lower tolerances. It is possible to have two plants of the same species placed side by side and have one freeze, while the other survives. Often some experimentation is necessary to determine what plants will work best for your garden. Cold Hardy Cacti Species (*Texas Native) Common Name Min. Temp. -
